Answer:
1
Step-by-step explanation:
1+3 = 4 4*7 = 28
it's 1 because 28/7 = 4 and you add 3 to the number so 1 + 3 = 4 * 7 = 28 is correct.
Hello,
I'm not going to do it for you, I'll explain you how to do it, so you can LEARN something. Like that is the equation of a line, we only need two points to draw it, they can be the x-intercept an y-intercept.
When we are looking for the x-intercept, y=0
And when we are looking for the y-intercept, x=0
Like you can see in the picture, so replace x=0 to find the y-intrcept and y=0 to find the x-intercept and join them, as you saw in the picture and there you have the graph.
If you have any trouble don't hesitate to tell me.

Answer:
x= -2
y=0
z= 1
Step-by-step explanation:
{-x+5y-10z=-8
2x-y+10z=6}
{2x-y+10z=6
-7x-3y-10y=4}
{-x+5y-10z=-8
2x-y+10z=6} = x+4y=-2
{2x-y+10z=6
-7x-3y-10y=4} = -5x-4y=10
{x+4y=-2
-5x-4y=-10}. =. y= 0 x= -2
substitute x and y in -x+5y-10z=-8
-(-2)+5(0)-10z=-8
solve for z
z= 1
(x,y,z) = (-2,0,1)
hope this helps
